To ml/f whom t may con-cern:

Be it known that I, WILLIAM HENRY CLARK, a citizen of the United States, residing at Salem, Columbiana county, Ohio, have invented certain new and useful Improvements in Wheels, ot which the following is a specification.

This invention, pertaining to wheels for various uses, but contrived with special reterence for use on barrows and trucks, will be readily understood from the following description, taken in connection with the ae- 'companying drawing, which is a vertical diainetrical section et' a Wheel exemplifying my'invention. y In the drawing, 1 indicates a metallic disk; 2, a similar disk, the two being placed together back to back; 3outwartlly-turned tlanges on the periphery of the disks; 4, a tire engaging the. periphery ol theI llalngos; 5, portioiisol the twodisks coming into contact, the disks being formed with annular moldi l l l ings bringing themapart at places; (i, the [lat central portions olY the disksseparated from each other :it considerable distance, a

distance equal pi'el`erabl :it least to t.lie width ol' the tiro, 7, :i block, preferably ol' l wood, disposed`between the central portions tl" the disks and having a diameter greater I l pauded or riveted into these countersinlks to haii those disk portions; S, a spindle passing axially through and. tilting snugly in central i spindle is illustrated as being tubular, thus pei'l'oratioiis in the disks and block; .l, bell, shaped hollow hubs, their outer ends it'tling the spindle and their inner ends litting against the outer surl'aees ol the lhit central portions ol' the disks; il), nuts upon the spindle screwing lightl)V against; the outer ends olA the hubs; ll, -tiutwartily-projecting beads margining the llat centers ol the disks hubs; l2, a concentric molding projecting outwardlyr l'roni each "disk between the hub and the rim, the disks being se arated from each other at this point, the ino ding to have bell-shaped hubs, resulting in general surfaces of pleasing appearance, easy to clean, and of well-braced form. Block 7, being largentlia-n the llat central portions of the disks, takes corner-bearings against the inner surfaces of the curved annular portions 13 of the disks. The struct-ure thus presents bracing elements in compression extending from the hub ends to the points where the disks are in Contact at some considerable dist-ance radiallyfroin the wheel-axis, ,the heads" ll and the block taking the diagonal thrusts when the hubs join the disks. This is particularly important when a heavily-loaded Wheel is tipped to a considerable angle, as when dumping a barrow. The nuts upon the spindle cause the hubs tol clamp the llat centers of the disks against the block and give to the general center et"4 the structure ya very substantial character,

well suited to withstand the `strains of load and shock as well as side strains. The s indlo is manifestly renewable with ease. ".lhe nuts are to hc screwed up tightl)v to bring the connected parts under strain, and suitable provision should be made to prevent the loosening of t he nuts. Anyv appropriate nutloek system may be employed, the illustration showingr the nutseountersunk upon their exterior, the metal el" the spindle beine' exprevent the backing ell' ol' the nuts. The
